Notes from Apache HTTPD Source Code

thought I'd take a break from coding and post about how open-source is such a great tool for finding the best answers to the toughest questions,

/** is the status code informational */
#define ap_is_HTTP_INFO(x)         (((x) >= 100)&&((x) < 200))
/** is the status code OK ?*/
 
#define ap_is_HTTP_SUCCESS(x)      (((x) >= 200)&&((x) < 300))
/** is the status code a redirect */
#define ap_is_HTTP_REDIRECT(x)     (((x) >= 300)&&((x) < 400))
 
/** is the status code a error (client or server) */
#define ap_is_HTTP_ERROR(x)        (((x) >= 400)&&((x) < 600))
/** is the status code a client error  */
 
#define ap_is_HTTP_CLIENT_ERROR(x) (((x) >= 400)&&((x) < 500))
/** is the status code a server error  */
#define ap_is_HTTP_SERVER_ERROR(x) (((x) >= 500)&&((x) < 600))
 
/** is the status code a (potentially) valid response code?  */

Smart HTTP and HTTPS .htaccess Rewrite

This is freaking sweet if you use SSL I promise you! Basically instead of having to check for HTTPS using a RewriteCond %{HTTPS} =on for every redirect that can be either HTTP or HTTPS, I set an environment variable once with the value "http" or "https" if HTTP or HTTPS is being used for that request, and use that env variable in the RewriteRule.

Hacking and Hackers

The use of "hacker" to mean "security breaker" is a confusion on the part of the mass media. We hackers refuse to recognize that meaning, and continue using the word to mean someone who loves to program, someone who enjoys playful cleverness, or the combination of the two. See my article, On Hacking.
